I know several trans people at various stages of transitioning, but I’m not super close with any of them so I can’t really offer any advice to you on that front other than to say that you’ve got my support!
What I will say is, figuring yourself out isn’t easy, so don’t rush into anything. Take some time to examine your thoughts and process your emotions about it. I wouldn’t come out to everyone until you’re more certain about things, but if you have someone close to you that you can talk to in order to help you through the “figuring shit out” part, that could be valuable.
